1. A computer-implemented method comprising:

  • receiving or capturing an image of a room from a perspective of a non-line-of-sight gesture-recognition system;

    receiving or determining dimensions of the room; and

    determining, based at least in part on the image and the dimensions of the room, a volume of the room in which there is no line-of-sight to the non-line-of-sight gesture-recognition system; and

    determining, by providing radar transmissions from the non-line-of-sight gesture-recognition system and into the room, a set of transmission paths sufficient to cause a reflected radar field to be provided within at least a portion of the volume, the reflected radar field enabling capture of gesture interactions with the reflected radar field.
